<h2>EPICA Dome C Ice Core 800KYr Temperature Estimates</h2>

<h3>Description</h3>

<p>Temperature record, using Deuterium as a proxy, from the EPICA
(European Project for Ice Coring in Antarctica) Dome C ice core
covering 0 to 800 kyr BP.    
</p>


<h3>Usage</h3>

<pre>data(edcT)</pre>


<h3>Format</h3>

<p>A data frame with 5788 observations on the following 5 variables.
</p>

<dl>
<dt><code>Bag</code></dt><dd><p>Bag number</p>
</dd>
<dt><code>ztop</code></dt><dd><p>Top depth (m)</p>
</dd>
<dt><code>Age</code></dt><dd><p>Years before 1950</p>
</dd>
<dt><code>Deuterium</code></dt><dd><p>Deuterium dD data</p>
</dd>
<dt><code>dT</code></dt><dd><p>Temperature difference from the average of the last
1000 years ~ -54.5degC</p>
</dd>
</dl>



<h3>Details</h3>

<p>Temperature was estimated from the deuterium data, after making various
corrections.
